SPECIFICATION forming part of Letters Patent No. 419,566, dated January14, 1890.

Application filed January 10, 1889, Serial No. 296,043. (No model.) i

To all whom it may concern.-

Be it known that 1, WILLIAM SCOTT, a citizen of the United States ofAmerica, and a resident of the town of Medford, in the county ofMiddlesex and State of Massachusetts, have invented certain new anduseful Improvements in Water-Closets, of which the following is a full,clear, and exact description.

This invention relates to valves more particularly intended for use incontrolling and regulating the discharge of water from watertanks in thewater systems of dwelling-houses and other buildings, &c., and tomechanisms for operating 'the valves to open them and allow them toclose.

As to the valve, theinvention in substance consists in the combination,with a water-tank having a discharge-pipe leading from it, of achambered opening and closing valve which seats across and on said pipe,made, preferably, of hard vulcanized india-rubber and otherwise ofsuitable character to float in the water of the tank when opened, and ishinged at one side of and opens upward from said pipe, and has openingsin its seating side that with the valve closed severally makecommunication between the chamber of the valve and the discharge-pipe,and with the valve opened severally make communication between thechamber of the valve and the water contained in the tank,but atdiiterent heights or levels thereof, so as to act as passages for theescape of the air contained in the valve and for the inlet of water fromthe tank to the valve, and thereby weighting it to secure its closing,on which the Water then in the valve discharges itself through saidopenings into the discharge-pipe, the valve remaining closed until againopened, all substantially as hereinafter described.

As tothe mechanism for operating the valve to open it, this invention insubstance consists in the combination, with a Water-tank having adischarge-pipe leading from it and an opening and closing valve whichseats across and on and is hinged at one side of and opens upward fromsaid pipe, of a yoke hinged independently of said valve to swing upwardand downward and on its upward swing to engage said valve a-nd carry itwith it and then to leave it, and on its downward swing to swingindependently of and separate from said valve, and thus to return to itsnormal position, leaving the valve free to its own movement forreturning to its seat, all substantially as hereinafter described.

In the drawings forming-part of this specification the contrivances ofthis invention are illustrated. v

Figure 1 is a side elevation of a valve having all the features of thisinvention and of. the swinging yoke fol-opening it and leaving it freeto close. Fig. 2 is a plan view. Fig. 3 is a central vertical section,line 3 3, Fig. 2. Fig. 4 is a vertical section of a water-tank and itsdischarge-pipe with a valve of this invention applied to said pipe andshown in itsclosed and opened positions. 7

In the drawings, A is a water-tank-sueh, for instance, as used forwater-closet bowls in the water systems of dwelling-houses, buildings,&c. v

Bis the discharge-pipe of the tank to be connected to awater-closetbowl, and C is the overflow-pipe of the tank in'communication with thedischarge-pipe B, all as well known,

and therefore needing no particular description.

D is an opening and closing valve for th discharge-pipe and seating onand across its end E, opening to the tank. The valve D is chambered, andit is made of hard vulcanized india-rubber, by which the utmostlightness, combined with all the necessary strength and stiffness, issecured, and, compared with metals of which chambered valves haveheretofore been made, also economy in material and reduction in sizerequisite to impart to it the buoyancy and floating capacity desired.

F is an ear projection at one side of the valve D and pivoted to astationary part G of the overflowpipe, and with it making a hinge of thevalve for the valve to be opened upward from its seat on thedischarge-pipe. The bottom wall or seating side H of the valve D has aWasher J, of india-rubber, leather, or other suitable material, forpackingand securing close joint between it and the discharge-pipe.

side H and packing J of valve, and at opposite sides of the center ofthe valve in'a line intersecting the axial line of swing of the valve.

M is a plug screwing through the top wall of the valve and in line withone K of the openings K L, for the purpose of regulating the extent orarea of said opening. WVith the valve closed both openings K L are opento the discharge-pipe of the tank. Again, with the valve opened bothopenings K L are open to the water contained in the tank, and theopening K the nearer to its hinge F G is at a height or level in thetank lower than that of its other opening L, the farther from its hinge,by means of which, as the pressure of water at the lower opening isobviously greater than that at the upper opening of the valve, becauseof the greater height of watercolumn at the lower opening as comparedwith that at the upper opening of the valve, the valve becomes chargedwith water from the tank, entering it at the lower opening, and thecontained air of the valve escaping at the upper opening, and thus thevalve, otherwise capable of floating, is weighted to a degree to secureits closing, on which the water with which the valve was charged thenpasses from the valve into the discharge-pipe, and the valve becomesready for another opening and closing, as before.

N is a ring or yoke encircling the valve and at the hinged side of thevalve hinged, as at 0, and opposite thereto, in its normal position, atrest'on a ledge P of the discharge-pipe of the tank and thereconnectedas, for illustration,

by a-rod or wire Q-to a suitable lever mechanism, Fig. 1, by which toswing said yoke upward and leave it free to fall.

Various forms and arrangements of lever mechanisms for lifting the yokemay be employed-for example, such as embraced in Letters Patent of theUnited States, issued to me, No. 277,455, Reissue No. 10,653, No.331,556, No. 331,557, No. 331,558, and No. 3Sl,087-or other suitablekinds of lever mechanism The lever mechanism, however, forms no part ofthis invention.

The yoke as it is swung upward abuts against side projecting horizontalpins R R of the valve, and thus the valve is carried with it and openedand so left, while the yoke returns to its normal position.

From the above, plainly, the valve, after being opened and while closingand closed, is absolutely free of all connection with the valve-liftingmechanism-a quite important advantage, avoiding, as it necessarily must,all possible hinderances to its free action.

Having thus described my invention,what I claim, and desire to secure byLetters Patent of the United States, is-

1. The combination, with the discharge-pipe of a water-tank, of achambered valve to open and close said discharge, and hinged at one sideand in its seating side, having openings at opposite points thereof andat unequal distances from the axial line of its swing, substantially asdescribed, for the purpose specified.

2. The combination, with the disch arge-pipe of a water-tank, of a valveto open and close said discharge, hinged at one side, and a yoke 'N,independently hinged and adapted to engage the valve to open it andleave it free to close, substantially as described, for the purposespecified.

In testimony whereof 'I have hereunto set my hand in the presence of twosubscribing witnesses. A

WILLIAM SCOTT.
